Embodiments Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 5 of the accompanying drawings showing embodiments thereof.

First, in FIG. 1, an apparatus according to one embodiment of the present invention is schematically shown in longitudinal section, which generally consists of spaced apart, parallel arrangement, as shown in the figure. A pair of disc-shaped side walls 1 ₁ , 1 ₂
and a hollow cylindrical outer box 1 consisting of a cylindrical peripheral wall ₁₃ interconnecting their peripheries,
Inside this, a rotating drum 2 is rotatably attached to one side wall 1 ₁ of the outer box ₁ via a rotating shaft 3. A bearing member 4 for rotatably supporting the rotary shaft 3 is fixed to the inside of the outer box 1 so as to stand upright. The rotating drum 2 also has a disc-shaped part 20 fixed on one surface with the rotating shaft 3 upright in the center thereof, and a disc-shaped part ₂₀ fixed to the outer circumference at right angles to the disc-shaped part 20 in the width direction. A cylindrical plate-shaped bottom wall 2 ₁ is fixed along the central dividing surface, and a cylindrical plate-shaped bottom wall 2 ₁ is fixed along the inner periphery and protrudes radially from each opposing periphery of the bottom wall 2 1 so as to stand upright therefrom. It is formed from a pair of annular peripheral walls 2 ₂ , and these bottom walls 2 ₁ and a pair of peripheral walls 2 ₂
A hollow annular cord storage section 2 ₃ is formed between the two, and a disc-shaped section 2 ₀ of the rotating drum 2 is formed therebetween.
The surface on which the rotating shaft 3 is not provided and the bottom wall 2 thereof
In the cylindrical space formed by the inner periphery of the bottom wall ₂₁ , there is a convex arcuate plate 51 having an outer diameter approximately equal to the inner diameter of the bottom wall ₂₁ , and a concave arcuate plate ₅₁ having an inner diameter smaller than that. A locking drum 5 having a hollow box shape with a so-called tome-shaped planar outline, which is constructed by combining 5 _{and 2} , connects the open periphery of the convex arc shape ₅₁ to the other part of the outer box 1. It is rotatably supported by a bearing, for example, by being brought into contact with the inner periphery of a circular opening 1 ₂₁ opened in the side wall 1 ₂ . Furthermore, in this cylindrical space, depending on the inner diameter of the concave arcuate plate 5 ₂ , a hollow cylindrical locking tool 6 having a small outer diameter is installed at a distance from the inner diameter surface of the concave arcuate plate surface 5 ₂ . Although the locking device 6 is arranged in a fixed position, the locking device 6 is rotatable together with the locking drum 5, but is attached to the locking drum 5 as appropriate so that it can be freely moved in and out of the locking drum 5 in the axial direction. The bottom wall 2 ₁ of the rotating drum 2 is provided with an arc-shaped section along the disc-shaped portion 2 ₀ that is slightly longer than the diameter of the locking tool 6 by a certain width. By cutting it out, an opening 7 for inserting and removing the cord is formed, and an opening 8 for inserting and removing the cord is also formed in the cylindrical side wall ₁₃ of the outer box 1.

Furthermore, in this embodiment, between the outer surface of the cylindrical bearing member 4 that rotatably supports the rotating shaft 3 of the rotating drum 2 and the bottom wall 2 ₁ of the rotating drum 2,
A mainspring spring 10 is arranged to surround the bearing member 4, each end of which is fixed to the bearing member 4 and the bottom wall ₂₁ , respectively. A stopper 11 made of, for example, a screw member is provided between them for controlling the rotation of the rotating drum 2.

One embodiment of the present invention has such a configuration, but the device according to this embodiment has, for example, a third
As shown in the figure, the electric cord 20 that interconnects the two OA devices OA ₁ and OA ₂ is stored in the cord storage section 2 ₃ of the rotating drum 2 of this device. In order to store the device 30, first, as shown in _FIGS .
The rotary drum 2 is rotated so that the cord insertion/removal opening 7 formed in the bottom wall ₂₁ of the rotary drum 2 are aligned vertically, and the locking drum 5 is
is rotated relative to the rotating drum 2 so that the concave arc-shaped plate ₅₁ faces the cord insertion/extraction opening 7 of the rotating drum 2, and at the same time, the locking tool 6 is rotated.
, whose bottom surface 6 ₁ is the disc-shaped portion 2 ₀ of the rotating drum 2
Keep it away from the surface where the rotating shaft 3 is not provided. After the device 30 is in this prepared state, the electrical cord 20 to be stored is folded in half approximately at the center of its length, as shown in _FIG . Inside the device 30, a cord is inserted through an opening 8 formed in the outer box 1 and is suspended into the apparatus 30, and then through an opening 7 formed in the bottom wall ₂₁ of the rotary drum 2. The leading end portion of the concave arc plate 5 of the locking drum 5
₂ , the locking device 6 is formed near the bifold portion ₂₀₀ of the cord 20,
The bottom surface 6 of the space has an approximately semicircular outline.
₁ comes into contact with the disc-shaped portion ₂₀ of the rotating drum 2. As a result, the bifold portion ₂₀₀ of the cord 20 is restrained between the circumferential surfaces of the locking drum 5 and the locking tool 6, so that the locking drum 5
was rotated with respect to the rotating drum 2 in the counterclockwise direction as seen in FIG. 4 in the direction of arrow X, and as shown in FIG. 5, it was turned approximately 180° from the position shown in FIG. Bring it into position. In this state, the electric cord 20 is connected to the concave arc-shaped plate 5 ₂ of the locking drum 5 in the shape of a hollow box and the locking tool 6 .
It comes into the wedge-shaped gap formed between the outer circumferential surface of the drum 2 and is firmly held by the rotating drum 2. In this state, continue to move the rotating drum 2 with respect to the outer box 1 in the direction of the arrow X. When rotated in the direction _of
It is wound around the outer periphery of the cord storage section 23 and stored inside the cord storage section ₂₃ . In this case, the rotating drum 2 and
A mainspring spring 10 is installed between the outer box 1 and the mainspring spring 10, so as the rotating drum 2 rotates, the mainspring spring 10 is also wound tightly or rewound. Therefore, by appropriately selecting this, it becomes possible to reduce the rotational torque that is required to be applied to the rotating drum 2 when storing the cord 20.

Conversely, when pulling out the electrical cord 20 housed in the device 30 of the present invention from the device 30, it is sufficient to pull the cord 20 to the outside of the outer box 1. In the final part of the process, the locking drum 5 changes from the state shown in FIG. 5 to the state shown in FIG _. By separating the electrical cord 20 from the electrical cord 20, the entire electrical cord 20 can be taken out from the device 30 of the present invention. In this case, as the rotating drum 2 rotates, the mainspring spring 10 is also rotated, so that it is wound tightly or rewound. In order to control the action of the mainspring spring 20 at this time, the stopper 11 shall be operated as appropriate.

In addition, in this embodiment, the mainspring spring 10
Although it is assumed that the main spring 10 is installed, the mainspring spring 10 may be omitted.

Effects of the Invention Since the present invention has the above-mentioned configuration and operation, it is clear that it can exhibit the following effects. That is, when storing the electrical cord, the electrical cord is folded in two and restrained within the bottom wall of the rotating drum at this portion, and the electrical cord is stored between the bottom wall of the rotating drum and the annular peripheral wall. This is done in a hollow cylindrical cord storage section, so the storage space for electrical cords is organized and orderly, and the overall size can be reduced.The electrical cord storage process is easy.A main spring is used as appropriate. By doing so,
It is possible to store the cord with a relatively small external force. It is possible to store an electrical cord of a desired length inside the cord storage section of the rotating drum. There is no need for a contact mechanism that rotates and moves. Therefore, there is no occurrence of unexpected accidents such as instantaneous power outages that may occur when moving the cord.
